CATTLE-GUARD.

SPECIFICATION forming part of Letters Patent No. 500,730, dated July 4,1893.

Application filed December 7,1892. Serial No. 454,353. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN WoLHAUP- TER, a subject of the Queen ofGreat Britain, residing at Morgan Park, county of Cook, State ofIllinois, have invented a certain new and useful Improvement inCattle-Guards; and I declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it pertains to make and use the same, referencebeing had to the accompanying drawings, which form a part of thisspecification.

My invention has for its object the produc-- tion of a rail-way cattleguard of that class in which a series of guard bars made of plates ofmetal, are placed in an inclined position, and parallel with each other.

This invention relates first to the form of the upper edge of the guardbars, and secondly, to the manner of securing the guard bars to thecross bars.

In the drawings: Figure l. is a plan view of my guard. Fig. 2. is ahorizontal section; Fig. 3. a view looking at the construction shown inFig. 1. from the direction of the arrow with the rail removed; Fig. 4..a detail of the cross bar; Figs. 5. and 6. details showing two ways ofsecuring the guard bar to the cross bar. Figs. 7. 8. 9. and 10. showdifferent ways of shaping the upper edge of the guard bar.

In carrying out the invention A represents the track rails; B the guardbars of my guard.

'O are the cross bars, preferably shaped in cross section as shown inFigs. 5. and 6., although instead of a cross shape, they might be angleor T shape. The upwardly projecting flange is provided with inclinedslots 0. The guard bars are set in these inclined slots and are held tothe cross bars in the following manner:-In the lower edge of the guardbar the metal is punched out, or up-set, as at I), thus providing ashoulder which bears against the upwardly projecting flange c of thecross bar. The metal of the lower edge of the guard bar on the oppositeside of the flange 0 may either be up-set as at b Fig. 6, and bent downunderneath the flange c of the cross bar, or an orifice b Fig. 5. may bepunched in the lower edge and a channel iron or key D be extendedthrough to engage the lower edge of the guard bar B with the cross bar.

It will be observed that in Fig. 1 the upper edges of the guard bars arescalloped as at B, the scallops of one bar being out of alignment withthe scallops ot' the next adjacent bar. It is obvious that the upperedge of each guard bar may have plain scallops, as in Fig. 1., or theprojections may be provided with V shaped recesses E Fig. 7, and thedepressions provided with teeth F Fig.7, or the depressions shown may beprovided with. teeth Fig. 8, or the scallops or projections may beangular in shape as shown at G Fig. 9, and they may, or may not beprovided with recesses H and teeth J Fig. 10. These various formsobviously come within the scope of my invention which lies essentiallyin the provision of inclined guard bars, having a series ofenlargements, or scallops, which when placed in the inclined positionindicated will have one of the enlargements or projections overlapping adepression or recess in the next adjacent bar. With this form ofconstruction an exceedingly effective guard is produced, while at thesame time the cost is materially lessened, from the fact that a singlesheet of metal, by being cut longitudinally through the middle by dies,or otherwise can be made into two of the guard bars.

I am aware that cattle guards have heretofore been constructed in whichvertical bars were provided with scallops that alternated with eachother in transverse alignment. I am also aware that inclined bars havebeen provided with saw teeth, and these of course I do not claim, but

What I claim is- 1. In a cattle guard the combination of a series ofguard bars extending substantially parallel with, and adjacent to eachother,said guard bars being in an inclined position, and the upper edgeprovided with a series of seallops, a projection on one bar over-lappingand being in transverse alignment with a depression on the next adjacentbar, substantially as described.

2. In a cattle guard the combination of a series of guard bars extendingsubstantially parallel with each other, the upper edge of the barbeingprovided with enlargements or scallops and the depression betweeneach scallop being provided with a sharp tooth, substantially asdescribed.

3. In a cattle guard the combination of a series of guard bars extendingsubstantiallyparallel with, and adjacent to each other, said guard barsbeing in an inclined position, and the upper edge provided with aseriesof seallops, a projection on one bar over-lapping and being intransverse alignment with a depression on the next adjacent bar, thedepression between each projection or scallop being provided with asharp tooth, substantially as described.

4. In a cattle guard the combination of a series of guard bars extendingsubstantially parallel With, and adjacent to each other, said guard barsbeing in an inclined position, and the upper edge provided with a seriesof seallops, a projection on one bar over-lappin g and being intransverse alignment with a depression on the next adjacent bar, eachprojection or scallop being provided with a V shaped recess and eachdepression between the seallops being provided with a sharp tooth,substantially as described.

5. In a cattle guard the combination of the guard bars and cross bars,the latter having an upwardly projecting flange provided with inclinedslots in which the guard bars are placed, and one or more projections onthe guard bar formed by up-setting the metal to prevent longitudinaldisplacement of the guard bars, substantially as described.

6. In a cattle guard the combination of a series of guard bars and crossbars, the latter provided with an upwardly projecting flange havingslots in which the guard bars are placed, and with a horizontallyprojecting flange, the lower edge of the guard bars being provided withan orifice or slot and a bar or key having a flange to engage in theslot in the guard bar and to engage also the horizontal flange of thecross bar, substantially as described.

In testimony whereof I sign this specification in the presence of twowitnesses.

BENJAMIN WOLHAUPTER.
